Description

This product helps prevent discoloration of pool water due to iron, calcium, manganese, copper and other metals and minerals which may be present in the water supply. This product is an excellent general purpose sequestrant which helps protect plumbing and pool walls from rust, stain and scale. It should be used for all pool openings and closings and throughout the season as needed. For initial filling of pool, if iron or other metallic contaminants are suspected, add one quart of Metal Free for each 10,000 gallons of pool water. Add Metal Free while the pool is being filled and before chlorine is added. To correct an existing colored water problem (due to the presence of minerals in the pool water), first close the pool to all swimmers. Leave the filter pump running. Stop chlorinating the pool and allow the chlorine level to drop to zero. Lower the pH of the pool water to 6.8 with pH Lower, lowering the pH will re-dissolve the metallic impurities. Add one quart of Metal Free per 10,000 gallons of water and allow the pool water to circulate overnight, or until the water is clear. Re-adjust the pH of the pool water between 7.2-7.8 with pH Rise. Begin normal chlorination and pool operation. Swimming may resume when chlorine residual is 1.0-3.0 ppm. To make up for loss of Metal Free due to backwashing and/or splash-out, add one quart of Metal Free for each 20,000 gallons of pool water, once each month.

  • Iron and Copper removed
Size: 1-Pack Style: Metal Out
Used this product on my salt water in ground pool three weeks ago. Worked great. Metals pulled from the water, no changes to chemicals ppm noted. Brushing stained areas greatly reduced long standing stains. Will continue brushing areas over next weeks. Very pleased.

  • Works so much better than all the others - be certain to get Premium concentrated bottle
Size: 1-Pack Style: Premium Metal Out
Due to high levels of Iron/Manganese/Sulfur in my well water, this year I decided to try this Premium metal out. Once the pool was filled with water I added the recommended amount, ran the filter, backwashed and repeated with same dosage and about 6 hours filter time. Then I tested levels again for hardness and PH. I added calcium per my own readings. This year when I added the shock I didn't get an entire pool of chocolate milk colored water - it was a pale brownish/green hue for which I added the rest of the bottle of Premium Metal remover and ran filter overnight, backwashed in the morning and checked levels and all was crystal clear. I could now place a chlorine floater in the pool and begin my weekly doses of E-Z Pools and call it all good for the season. This Premium metal out was far better that the regular one. It worked so much faster. If you have well water, I fully recommend this product!! ... show more

  • Almost worked
Size: 1-Pack Style: Metal Out
I have iron from well water. This product showed improvement but it’s not all gone. (The green is a reflection of trees) One bottle should treat 10,000 gallons. My pool is an above ground 3,400 gallon. I first added the appropriate amount for my size pool but saw no difference after 24 hours with the pump running nonstop. I then added the rest of the bottle, pump running continuously for the next 32 hours. The pic is the result. A definite improvement (wish I had a before pic) but not crystal clear. I’m at a loss. BTW chlorine was at 0. ... show more

  • BEST PRODUCT FOR WELL WATER!!!
Size: 1-Pack Style: Metal Out
This product is absolutely amazing! Day, one of our pool being filled I shocked it and five minutes after it turned completely brown. We have a lot of iron in our well water, which I wasn’t aware of. Once I put this bottle in no joke within a day it cleared my pool. Below our pictures of day one, day three in the morning, and day three in the evening. So impressed and I will keep stocked on this at all times! ... show more

  • More like "Metal In"
Size: 1-Pack Style: Metal Out
From the name you would think this separates the metal from the water, allowing it to be filtered (or so least I did). The reality is the opposite. The chemical redissolves the metal after it has been oxidized (e.g., by shock). But as soon as you bring the chlorine back up, the brown color returns. Super frustrating. It took me 2 years of frustration to realize what is actually going on and now I'm trying out a different solution to actually remove the iron. ... show more

  • It works!
Size: 1-Pack Style: Premium Metal Out
It works! We put about a cup in and kept the filter running 24\7 for 3 days and cleaned the filter 2 times a day and it did the trick!
